4Speciiication of Letters Patent. Patented Sept. 20, 1910 Application filed May 28, 1909. Serial No. 498,942.

.To all whom 'it may concern:

f Be it known that I, RICHARD BIEL, a subject of .the German Emperor, and resident of Itzehoe, Germany, have invented certain new and useful Improvements 1n Windows.'

of, which the following is a specification.

My invention relates generally to windows articularly to sash-windows ofV the English easement type.

Y vA primary ob'ect of my invention is to provide 4an improved sashfwindow which differs vfrom known forms in that the bottom end of each longitudinal groove opens into a transverse groove into which the pin attached to the'sash is positively introduced in the lowest position of the sash owing to l the sash meeting with .a resistance at the bottom of the frame when being tilted.

Some illustrative embodiments of my invention are represented by way of example in the accompanying drawing, wherein Figure 1 is a. vertical section throughmy improved sash-window, and Fig. 2 is a like view of the lower part on a. larger scale showin the bottom sash tilted over; Fig. 3

is asi e elevation of thel left .jamb-liniug With a' modified form of the dev1ce enabling the sash lto be opened, and Fig. 4 is a front `elevation ofthe device shown in Fig. 3, whereas Fig. '5 is a section through the left jamb-lining showingthe device according to Figs. 3 and 4 in position of the sash -allowing the same to be raised; Fig. 6 is a side elevation' of a movable guide, Fig. 7 a rear elevation of same, and Fig. 8 a top A plan view of the saine; Fig. 9 shows a modilguide pin 5 presses 'a ainst the free end of aV spring. 7 whichten s to revent the sash being rocked, said recess eing protected from undue wear by a vmetal plate 8 cut away correspondingly.4

In order to rock sash 6, it has only to be pushed down as far 4as possiblein the groove 2 orB and then tilted forward when it rocks forward under the action of its own wei ht. YBit Vit is-l only necessary to tilt the sas a very slight amount to cause it to be automatically secured against the draft of the cord ofthe counter oise. Namely, it only requires a slight inc ination of the sash for guide pin 5 to be brought under the edge 9 at the junction of groove 2 and recess 4, as at the lower ed e of the bottom lside of the sash isa specia .rim 10 which rests` against v the facel 11 of the sill molding 12 and in consequence of the displacement' of the axis of rotation of the sash caused thereby, guide pin 5 is moved into recess 4. On theother l hand, the tendency of the pressed spring 7 is to place the sash upright lby forcin the guide pin out of the cavity. As the e ge 9 projects considerably and only' 'ust allows guide pin 5to pass, all possibi ity of the sash swingin down of its own accord or of its being puldup by the p'ull of the counterpoise is-thus avoided.

When the lower lsash cannot for any reason be raised suliciently high, as in the case of round-headed windows, in order to swing the top sash under the elevated lower sash, another cavity or recess 13 .similar tothe lower recess 4 may be irranged at a suitable y v part of groove 3 and pr tected by a similarly cut plate 14, as shown in dotted lilies. Obviously, in this event this plate must separate. the top part of groove 2 from the lower part so that the top sash can be rocked parallel with the lower sash. Of course the sashes have a guide pin at their upper ends as well as those at their lower ends, the former serving for guiding the sashes, and the latter as pivots. In this illustrative enibodiment the fillet 16 between the two grooves 2 and 3 has in it a transverse groove "17 through which the upper guide pm 23 can slide so that the sash in question can be tilted. The two'sashes are ke tin their closed position by a Z-shaped bo t' 18 which engages in a cavity in the jamb-llning.

Referring to Figs. 3 4 and 5, instead 'of the branch groove 17 (Fig. 1), I preferably use an angular metal strlp 19 at the outer edge of the jamb-lining anda somewhat p curved metal strip 20 on the Vfillet 16 separating the grooves 2 and 3. Ina correspond- 111g position on the sash is placed a beveled 'sprin -pressed bolt 21 pressing on the-strip 20 w en the sash is closed. These strips 19 and 20 form abutments which prevent thesash tilting automatically at the 'wrong time. They are arranged, relatively' to the sash'in its lowest position, in which this can f 4t'ore the sash can be lowered.

only be tilted inward, at the height ofthe bolt 21. The latter" is pressed against the strip 2O with a somewhat tensioned spring, in order that it can snap into the groove when the sash is pulled and here serves as a guide pin when the sash is pulled upward.

Further. the bolt 21 cannot be entirely withfillet between the groove 2 and the front edgecf the jamb-lining. The angle 22 of this stripv is so deep that the" bol-t .21 can pass through the same. may be provided on the jamb-lining and strips 19 and 20 on the sash; or, as shown in Figs. 9 and 10, a pin 30 may be attached to the lower part of casing 1, the end of the pin projecting .into a recess or cavity 3l in a corresponding part of the sash, to prevent the sash -from being tilted inwardly except in its lowest position; the end ofthe cavity can be closed by a band spring 33, for eX ample, Afastened 'to' the sash by the eye 32.

The recess 22 is arranged in strip 19 in such 'manner that lbolt 21 cannot `slide through it but must first be drawn back. be-

The branch groove I1'?" canl be dispensed with if use is made of the spring guide or catch shown in Figs. 6, 7 and 8, instead of the' guide'pin 23. This spring guide is screwed onto the edge of the sash and comprises a slotted metal. plate 24 having upper and lower4 lugs projecting therefrom at right angles, and a curved pointed plate 25 niovablymounted on said plate 24. This plate 25 has a pin 26 lying ,across its outer I' edges 28, said pin being surrounded bv a spring 27 whichv connects it with the' lugs -of the slotted vplate 24. The ends of the outer edges. 28 'of plate 25 prevent this from falling through the slot in plate 24, and at the same time; they form the pivot of the curved plate 25, this latter moving to one side or the/other when the sash is opened or 'closed as'-indicated by the arrows in Fig. 8. f

I claim 1. In 'a sash Window of the characteride- If desired bolt 21.

scribed, the combination of a :trame having longitudinal, lateral grooves terminating in two lateral, transverse, substantially horizontal recesses, a sash having two rims on.

either side of, and normally projecting below the top of,the bottom transverse member of said frame, and two lateral pins at the bottom of said sash movable in said grooves and said recesses. l

2. In a saslrwindow of the character described, the combination of a frame having longitudinal grooves terminating below in a transverse recess, a spring in said frame projecting into sai-d recess, a sash having limbs normally embracing the bottom member. of said fra-me, and a pin arranged on the side of said sash, movable in said groove and said recess, and adapted to abut against said spring when said sash is tilted in the lowest position thereof.

3. In a sash window of the character described, the combination of a frame having longitudinal grooves terminating below in a transverse recess, said longitudinal grooves being connected above said recess by a transverse groove, a spring in said frame projecting into said recess, a sash having limbs normally embracing the bottom member of said frame, and a pin arranged on the side of'A said sash, movable in said groove and said recess, and adapted to abut against said spring when said sash is tilted in the lowest normally embracing the vbottomr memberotl i said frame, and a pin arranged on the side of said sash, movable in said groove and said recess, and adapted to abut against said spring when said sash is tilted in the lowest position thereof, and guiding means movable in said longitudinal grooves. y

In testimony whereof I have hereunto set my hand in the presence of two subscribing RICHARD BIEL;
